CPC H04N 19/109 (2014.11) [H04N 19/132 (2014.11); H04N 19/159 (2014.11); H04N 19/176 (2014.11); H04N 19/52 (2014.11); H04N 19/70 (2014.11)] | 20 Claims |
1. A video data decoding device, comprising:
a memory, configured to store video data in a form of a bitstream; and
a video decoder, configured to:
parse a fourth indicator from a bitstream;
parse a fifth indicator from the bitstream when the fourth indicator indicates that a merge mode is used for inter prediction of a current picture block;
parse a sixth indicator from the bitstream when the fifth indicator indicates that a merge mode with motion vector difference (MMVD) is not used for the inter prediction of the current picture block, wherein the sixth indicator is a picture block-level indicator and is a third value or a fourth value, the third value indicating that a geometric prediction unit mode is allowed to be used for the inter prediction of the current picture block and the fourth value indicating that the geometric prediction unit mode is not allowed to be used for the inter prediction of the current picture block, wherein the geometric prediction unit mode includes a triangle prediction unit mode; and
perform the inter prediction on the current picture block to obtain a prediction block of the current picture block based on an inter prediction mode indicated by indicator information in the bitstream, wherein the indicator information comprises one or more of the fourth indicator, the fifth indicator, or the sixth indicator; and
obtain a reconstructed block of the current picture block based on the prediction block of the current picture block and a residual block obtained from the bitstream.
